Review & Description

If you're like most developers, you rely heavily on JavaScript to build interactive and quick-responding web applications. The problem is that all of those lines of JavaScript code can slow down your apps. This book reveals techniques and strategies to help you eliminate performance bottlenecks during development. You'll learn how to improve execution time, downloading, interaction with the DOM, page life cycle, and more.

Yahoo! frontend engineer Nicholas C. Zakas and five other JavaScript experts -- Ross Harmes, Julien Lecomte, Steven Levithan, Stoyan Stefanov, and Matt Sweeney -- demonstrate optimal ways to load code onto a page, and offer programming tips to help your JavaScript run as efficiently and quickly as possible. You'll learn the best practices to build and deploy your files to a production environment, and tools that can help you find problems once your site goes live.

• Identify problem code and use faster alternatives to accomplish the same task
• Improve scripts by learning how JavaScript stores and accesses data
• Implement JavaScript code so that it doesn't slow down interaction with the DOM
• Use optimization techniques to improve runtime performance
• Learn ways to ensure the UI is responsive at all times
• Achieve faster client-server communication
• Use a build system to minify files, and HTTP compression to deliver them to the browser

Review & Description

This Fifth Edition is completely revised and expanded to cover JavaScript as it is used in today's Web 2.0 applications. This book is both an example-driven programmer's guide and a keep-on-your-desk reference, with new chapters that explain everything you need to know to get the most out of JavaScript, including:

• Scripted HTTP and Ajax
• XML processing
• Client-side graphics using the canvas tag
• Namespaces in JavaScript--essential when writing complex programs
• Classes, closures, persistence, Flash, and JavaScript embedded in Java applications

Part I explains the core JavaScript language in detail. If you are new to JavaScript, it will teach you the language. If you are already a JavaScript programmer, Part I will sharpen your skills and deepen your understanding of the language.

Part II explains the scripting environment provided by web browsers, with a focus on DOM scripting with unobtrusive JavaScript. The broad and deep coverage of client-side JavaScript is illustrated with many sophisticated examples that demonstrate how to:

• Generate a table of contents for an HTML document
• Display DHTML animations
• Automate form validation
• Draw dynamic pie charts
• Make HTML elements draggable
• Define keyboard shortcuts for web applications
• Create Ajax-enabled tool tips
• Use XPath and XSLT on XML documents loaded with Ajax
• And much more

Part III is a complete reference for core JavaScript. It documents every class, object, constructor, method, function, property, and constant defined by JavaScript 1.5 and ECMAScript Version 3.

Part IV is a reference for client-side JavaScript, covering legacy web browser APIs, the standard Level 2 DOM API, and emerging standards such as the XMLHttpRequest object and the canvas tag.

More than 300,000 JavaScript programmers around the world have made this their indispensable reference book for building JavaScript applications.

"A must-have reference for expert JavaScript programmers...well-organized and detailed."
-- Brendan Eich, creator of JavaScript
